Flies

Flies have been part of The Sims series since the beginning. In The Sims 2 and The Sims 4: Eco Lifestyle, they can potentially swarm Sims and kill them. Flies in The Sims 4 are similar to the ones in The Sims 3. They hover over spoiled food and empty plates that haven't been put away or cleaned. As with The Sims 3, flies do not kill Sims in this game's base version, but they can make them uncomfortable. Flies will also appear around foul-scented laundry in The Sims 4: Laundry Day Stuff. Being eaten alive by flies is a form of death in The Sims 4: Eco Lifestyle. Unlike The Sims 2 equivalent, the Sim's body stays intact upon death. This death can occur if the Sim tries to do the Bond with Flies interaction. The ghost appears to always be surrounded by flies.
